Abstract (en)
There is provided an air conditioning apparatus whereby the growth of ice on the bottom plate of the outdoor unit can be suppressed without the use of a configuration that is distinguished from the refrigeration cycle, such as heater. An air conditioning apparatus (1) having a compressor (21), an outdoor heat exchanger (23), an outdoor motor-driven expansion valve (24), and an indoor heat exchanger (41) comprises outdoor fans (26), an outdoor unit casing (2B), and a hot-gas bypass circuit (H). The outdoor unit casing (2B) has a bottom plate (2b) and accommodates the outdoor heat exchanger (23) and the outdoor fans (26) in a space above the bottom plate (2b). The hot-gas bypass circuit (H) is disposed so as to pass below the outdoor fans (26) and below the outdoor heat exchanger (23), and bypasses a discharge tube (A) on the discharge side of the compressor (21), and at least any one of an indoor-side liquid tube (C) which extends from the indoor heat exchanger (41) to the outdoor motor-driven expansion valve (24), and an outdoor-side liquid tube (D) which extends from the outdoor motor-driven expansion valve (24) to the outdoor heat exchanger (23).
